Add AT_RECURSIVE from Linux 5.2 to fcntl.h
Commit Message
This patch adds the AT_RECURSIVE constant from Linux 5.2 to glibc's
fcntl.h. (Existing practice in glibc is that the AT_* constants go
directly in io/fcntl.h rather than somewhere OS-specific.)
Tested for x86_64.

Patch looks good to me. The definition matches the Linux sources.
